This module is designed to guide students in better understanding what electricity is and how it works by investigating electrical circuits.  The teacher will facilitate students' explorations as they use scientific terms to generate a summary of their experiences.  Throughout this unit, students will be guided in using practical materials such as wires, batteries, switches and light bulbs to better understand how electricity behaves in open and closed circuits. This module was developed by Stephanie Hooks as part of a Virginiga Commonwealth Universtiy STEM initiative sponsored by the Virginia Department of Education.

Description: Many people love roller coasters, but a portion of the population might prefer a slower, calmer ride experience.  Busch Gardens, a popular theme park in Williamsburg wants to offer a variety of rides that appeal to all ages and abilities.  Can you help them design and create a roller coaster that will move at a much slower pace than the typical roller coaster?  You will present your prototype in the form of a marble run built on the provided surface.  Think about the marble runs that you may have played with or built when you were younger.  Can you redesign a marble run that will take the marble the longest amount of time possible to reach the end without stopping?  At the conclusion, each group will test and time their marble runs.
